How do remove a class after revealing it?

March 18, 2024

I have a gif that I am trying to remove after 3 seconds of it being toggled on. Here is the breakdown.
• When the user clicks on the orange square it gets removed.
• A gif is toggled on.
• After 3 seconds
I want the gif to get removed and the brown circle toggle on.
I know I have to use the setTimeout method, but I do not know how to apply it. Can anyone help?
`

//Removes square
function remove(){
    this.remove();
    
}

//Adds gif
let gif = document.querySelector (".gif");

function showHide(){
    gif.classList.toggle("hide"); 
    
}

//Removes gif

*{
    padding:0;
    margin:0;
}
body{
    background-color:pink;
}
.parent{
    width:100vw;
    height:100vh;
    display: flex;
    justify-content: center;
    align-items: center;
}


.gif{
    border-radius: 20px;
    z-index: 1; 
}
.hide{
 display:none;
}
#square{
    width:200px;
    height:200px;
    position: absolute;
    background-color:orange; 
    border-radius: 20px;
    z-index: 2; 
    top:50%;
    left:50%;
    transform: translate(-50%,-50%);
    cursor: pointer;
}

.circle{
    width: 200px;
    height:200px;
    background-color:brown;
    border-radius: 50%;   
}

.hide_2{
    display:none;
   }

>Solution :

The issue is occurring because you are trying to show the circle which is a child of square after deleting the square. So making the square a sister element of the circle would get your job done.

//Removes square
function remove() {
  this.remove();

}

//Adds gif
let gif = document.querySelector(".gif");
let circle = document.querySelector(".circle")

function showHide() {
  gif.classList.toggle("hide");
  setTimeout(() => {
    gif.classList.toggle("hide");
    circle.classList.toggle("hide");
  }, 3000)

}

//Removes gif

* {
  padding: 0;
  margin: 0;
}

body {
  background-color: pink;
}

.parent {
  width: 100vw;
  height: 100vh;
  display: flex;
  justify-content: center;
  align-items: center;
}

.gif {
  border-radius: 20px;
  z-index: 1;
}

.hide {
  display: none;
}

#container {
  z-index: 2;
  top: 50%;
  left: 50%;
  transform: translate(-50%, -50%);
  cursor: pointer;
  position: absolute;
}

#square {
  width: 200px;
  height: 200px;
  background-color: orange;
  border-radius: 20px;
}

.circle {
  width: 200px;
  height: 200px;
  background-color: brown;
  border-radius: 50%;
}

.hide_2 {
  display: none;
}
